Ravago is a Belgian plastic producing company with its headquarters located in Luxembourg. The company is active in polymer and chemical distribution, building materials, recycling and compounding of plastic and elastomeric raw materials. Theodoros Roussis is the chief executive officer of the company.

In the United States, Ravago has six main subsidiary companies: Amco, Channel Prime Alliance, Entec, Muehlstein, Ravago Chemicals North America (RCNA) and Ravago Manufacturing Americas. Ravago has plastic compounding facilities in the United States located in Pennsylvania, Michigan, Ohio, Tennessee, and Texas.

History
On 25 April 1961, the company was founded by Raf Van Gorp and in 1965 he bought the premises of his former employer, a dynamite company (PRB: Poudre Reunion d'Arendonk, Belgique) in Arendonk.

Operations
Today, the Ravago group represents over 6,600,000 metric tons of annual polymer sales serving more than 50,000 active customers through 325+ locations across more than 55+ countries worldwide. Ravago’s production competence consists of 45+ manufacturing facilities of which 19 recycling and compounding plants in North America, Europe, Asia and Africa with a combined annual capacity of over 775,000 metric tons; 13 production plants in Europe that are offering finished products for the building sector and 7 plants and 6 application laboratories for the Chemicals business.


PA6尼龙塑料是一种化学物质,分子式是[-NH-(CH2)5-CO]n-。

PA6尼龙塑料的化学物理特性和 PA66 很相似,然而,它的熔点较低,而且工艺温度范围很宽。它的抗冲击性和抗溶解性比 PA66 要好,但吸湿性也更强。因为塑件的许多品质特性都要受到吸湿性的影响,因此使用 PA6 设计产品时要 充分考虑到这一点。为了提高 PA6 的机械特性,经常加入各种各样的改性剂。玻璃就是最常见的添加剂,有时 为了提高抗冲击性还加入合成橡胶,如 EPDM 和 SBR 等。对于没有添加剂的产品,PA6 的收缩率在 1%到 1.5% 之间。加入玻璃纤维添加剂可以使收缩率降低到 0.3%(但和流程相垂直的方向还要稍高一些)。成型组装的收缩率主要受材料结晶度和吸湿性影响。
